中文摘要:
      目的 将一种基于改性玫瑰茄花青素的新鲜度指示膜用于鲳鱼保鲜包装,并对指示膜的新鲜度指示效果进行评价。方法 以酰化改性玫瑰茄花青素为新鲜度指示剂,聚乙烯醇为涂布液基质,聚丙烯为基膜,制备新鲜度指示膜,研究其对挥发氨的响应性;以鲳鱼为研究对象进行包装应用试验。结果 随着挥发氨浓度的增大,指示膜颜色由红变紫再变绿;鲳鱼由新鲜级变为次新鲜级直至腐败级时,指示膜颜色均发生变化,具有与鲳鱼样本品质较强的关联性;指示薄膜颜色变化主成分得分呈明显的聚类趋势,与样本新鲜级相对应;基于偏最小二乘回归的TVB-N模型能有效预测鲳鱼的TVB-N值。结论 新鲜度指示膜具有用于鱼类产品新鲜度检测的潜力。
英文摘要:
      The paper aims to develop a freshness indicator film based on modified roselle anthocyanins for fresh-keeping packaging of catfish and evaluate the freshness indication effect of the indicator film. With acylated modified roselle anthocyanin as the freshness indicator, polyvinyl alcohol as the coating liquid matrix, and polypropylene as the base film, the freshness indicator film was prepared to study its response to volatile ammonia; and catfish packaging test was carried out. The results showed that with the increase of the concentration of volatile ammonia, the indicator film changed from red to purple and then to green; when the catfish changed from the fresh grade to the sub-fresh grade to the rotten grade, the color of the freshness indicator film also changed, which had strong correlation with the catfish sample quality; the principal component score of the color change of the indicating film showed a significant clustering trend, corresponding to the freshness level of the sample; the TVB-N model based on partial least squares regression can effectively predict the carp TVB-N value. The freshness indicator film has the potential to detect the freshness of fish product.
